DETAILED DESCRIPTION OF THE INVENTIONS

An embodiment of a urinal screen 10 is illustrated in FIG. 1. The urinalscreen 110 can be sized and shaped to fit into a urinal, toilet, orother bathroom appliance. As illustrated, the urinal screen 110 caninclude a first frame 114. In some embodiments, the screen 110 includesa second frame 116. The frames 114, 116 can be sized and shaped to fitover all or a portion of a drain of a toilet or urinal. The frame 114can include a plurality of openings 118 through a thickness of the frame114. As illustrated, the second frame 116 can include a plurality ofopenings 120 through the thickness of the second frame 116. In someembodiments, the urinal screen 110 includes a plurality of posts 122extending between the frames 114, 116.

The screen 110 can have a polygonal, elliptical, circular, or otheroverall shape. For example, as illustrated in FIG. 2, the screen 110 canhave a generally rectangular shape, though many other shapes arecontemplated (e.g., hexagons, pentagons, triangles, ellipses, or somecombination thereof). In some embodiments, the screen 110 is shaped tofit a particular urinal or toilet.

The frames 114, 116 and/or posts 122 can be constructed from a polymer,ceramic, or some other material. For example, one method ofmanufacturing an embodiment of the urinal screen 110 includes providingplastic or EVA material, which may have a melting point of not greaterthan 250° F., loading the plastic or EVA with at least 15% to about 75%by weight of fragrance material to produce a fragranced plastic or EVA,loading the fragrance at a stage conducted at temperatures such that thefragranced plastic or EVA is from at least 15% by weight fragrance uponcompletion of the loading stage, and molding the fragranced plastic orEVA into a urinal screen, sized and shaped to be disposed in a urinal,forming openings 118, 120 in the frames 114, 116, and forming posts 122.In some embodiments, the screen 110 is constructed from a materialincluding one or more additives such as anti-bacterial compounds,odor-neutralizers, silver ions, or other additives. In some embodiments,the screen 110 is at least partially manufactured using a 3-D printer.

The openings 118, 120 can have various shapes, including, but notlimited to, polygons (e.g., triangles, rectangles, pentagons, hexagons,etc.), ellipses, circles and/or some combination thereof. In someembodiments, each of the openings 118, 120 has a substantially identicalshape. In some embodiments, one or more of the openings 118, 120 have adifferent shape from one or more of the other openings.

In some embodiments, one or more of the openings 118 is defined by aperimeter having a plurality of sides 142 a and corners 146 a. Forexample, in the illustrated embodiment of FIG. 2, each of the openings118 is defined by six sides 142 a and six corners 146 a. In some cases,one or more of the sides 142 a is shared by two or more openings 118. Insome embodiments, all of the sides 142 a are either shared by aplurality of opening 118 or form a portion of the outer perimeter of theframe 114. The sides 142 a can each have substantially the same length.In some embodiments, some or all of the sides 142 a has a substantiallyconstant thickness along the length of the sides 142 a in a directionparallel to the frame 114 and perpendicular to the lengths of therespective sides 142 a. In some embodiments, one or more of the sides142 a has a different length from one or more of the other sides 142 a.In some configurations, each of the sides 142 a is connected to at leasttwo other sides 142 a at two corners 146 a. The openings 120 of thesecond frame 116 can have the same or similar characteristics (e.g., thecharacteristics of the sides 142 b and corners 146 b of the openings120) as the openings 118 of the first frame 114. In some embodiments,the perimeters of the respective openings 118, 120 form an array ofclosed and/or connected cells having sides 142 a, 142 b and corners 146a, 146 b. The closed/connected cells can form at least a majority (i.e.,more than 50%), at least ⅔ or at least ¾ of the surface area of thefirst frame 114. In some embodiments, the cells form the entirety of thearea of the first frame 114.

The urinal screen 110 can be constructed such that the openings 118 andoverall structure of the first frame 114 align with the openings 120 andoverall structure of the second frame 116 when viewed from above theurinal screen 110 (e.g., the view of FIG. 2) when the screen 110 is seton a flat horizontal surface. In some embodiments, one or more of theopenings 118 of the first frame 114 do not align with any openings 120of the second frame 116 and/or one of the openings 120 of the secondframe 116 do not align with any of the openings 118 of the first frame114. For example, one or more of the posts 122 can extend at anon-perpendicular angle with respect to and between the frames 114, 116.

As illustrated in FIG. 2, the openings 118 can occupy a large percentageof the overall surface area of the frame 114 as viewed in FIG. 2 (e.g.,viewed from above the frame 114). For example, the openings 118 canoccupy more than ⅛, more than 2/9, more than ⅓, more than ¼, more than⅜, more than ½, more than ⅝, more than ⅔, and/or more than ¾ of theoverall surface area of the frame 114 as viewed in FIG. 2. The openings120 of the second frame 116 can have similar or identical size andshapes to the openings 118 of the frame 114. Utilizing a large number ofopenings 118, 120 can reduce the overall weight of the urinal screen110.

In some embodiments, as illustrated in FIG. 3, the frames 114, 116 havea generally planar or flat shape. In some embodiments, the frame 114 hasan outer perimeter that matches an outer perimeter of the second frame116. In some embodiments, the frames 114, 116 have differing perimeters.The outer perimeters of the first and second frames 114, 116 can bealigned when observed from a perspective perpendicular to the first face116 a of the second frame 116. In some embodiments, the frames 114, 116are curved or otherwise shaped in non-planar fashion. For example, theframes 114, 116 can be molded in a non-planar shape to match thecontours of a urinal or toilet. Either or both of the frames 114, 116can be constructed from a flexible material configured to flex to matchor substantially match the contours of the surface onto which the urinalscreen 110 is installed. The first frame 114 can have a first framethickness 115. The second frame 116 can have a second frame thickness117. The second frame thickness 117 can be greater than, equal to, orless than the first frame thickness 115.

In some embodiments, the first frame thickness 115 is less than or equalto approximately ½ of the overall screen thickness 111 as measuredperpendicularly to a first surface 114 a (e.g., outer surface) of theframe 114 when the frame 114 or second frame 116 rests on a flatsurface. In some embodiments, the first frame thickness 115 is less thanor equal to ⅔, less than or equal to ⅝, less than or equal to ⅜, lessthan or equal to ⅓, less than or equal to ¼, less than or equal to 2/9,less than or equal to ⅛, less than or equal to 1/10, less than or equalto 1/12, less than or equal to 1/16, and/or less than or equal to 1/32of the overall screen thickness 111. In some cases, wherein the framethicknesses 115, 117 are relatively thin compared to the overallthickness 111 of the urinal screen 110, the overall weight of the urinalscreen 110 can be reduced.

As illustrated in FIG. 3, the urinal screen 110 can include a pluralityof posts 122. The posts 122 can extend between a second surface 114 b(e.g., inner surface) of the first frame 114 and a first surface 116 a(e.g., inner surface) of the second frame 116. In some cases, the posts122 extend perpendicularly from one or both of the second surface 114 bof the first frame 114 and the first surface 116 a of the second frame116. In some embodiments, the posts 122 extend at a non-perpendicularangle from one or both of the second surface 114 b of the first frame114 and the first surface 116 a of the second frame 116.

One or more of the posts 122 can have a substantially constantcross-section along the length of the post 122 as measured parallel tothe first surface 116 a of the second frame 116. In some embodiments, asillustrated in FIG. 4, one or more of the posts 122 can have a taperedshape. For example, one or more posts 122 can taper down from a maximumcross-section at or near the first surface 116 a of the second frame 116to a minimum cross-section at or near the second surface 114 b of thefirst frame 114. In some embodiments, the cross-section of the posts 122tapers down at a constant taper angle α. In some embodiments, the taperangle of the posts 122 is not constant. In some embodiments, thecross-section of one or more of the posts 122 has a maximum or minimumat a point along the length of the post 122 between the first surface116 a of the second frame and the second surface 114 b of the firstframe 114 (e.g., the mid-point of the post 122 between the first frame114 and the second frame 116).

As illustrated in FIG. 5, the posts 122 can extend from the second frame116 (e.g., from the first surface 116 a). In some embodiments, each ofthe posts 122 extends from a corner 146 b of an opening 120 of thesecond frame 116. In some embodiments, each of the posts 122 extendsfrom a side 142 b of an opening 120. In some embodiments, one or moreposts 122 extend from a side 142 b of an opening 120 and one or moreposts extend from a corner 146 b of an opening 120. The posts 122 canconnect similarly to the sides 142 a and/or corners 142 b of the firstframe 114 (e.g., from the second surface 114 b of the first frame 114).

One or more of the posts 122 can have a height different from one ormore of the other posts. For example, one or more posts 122 can beshorter than one or more other posts 122. In some embodiments, one ormore of the shorter posts 122 connects to both the first frame 114(e.g., to the second surface 114 b) and the second frame 116 (e.g., tothe first surface 116 b). In some such embodiments, the overall heightof the screen 110 can vary across the first surface 114 a of the firstframe 114 and/or across the second surface 116 b of the second frame116. Varying the overall height of the screen 110 can reduce surfacecontact between surface of the installation site (e.g., urinal ortoilet) and the frame 114, 116 in contact with the surface. Reducingsuch surface contact can reduce the likelihood that the screen 110 wouldmove on the installation surface. In some embodiments, varying theoverall height of the screen 110 can reduce splashing from the screen110 when in use. The first surface 114 a of the first frame 114 and/orthe second surface 116 b of the second frame 116 can include one or moresurface features (e.g., bumps, protrusions, ribs, nubs, knobs)configured to reduce the likelihood that the screen 110 would move onthe installation surface when in use. In some embodiments, the use ofvariable-height posts 122 and/or use of one or more surface features onthe frames 114, 116 can provide one or more gaps between theinstallation surface and the frame 114, 116 in contact with theinstallation surface. The one or more gaps can be small enough toinhibit passage of debris between the urinal screen 110 and theinstallation surface while allowing passage of liquid between the urinalscreen 110 and the installation surface.

In some embodiments, one or more of the posts 112 extend between thefirst and second frames 114, 116 and are connected to only one of thefirst and second frames 114, 116. In some such embodiments, flexibilityof the screen 110 can be increased and/or splash from the screen 110 canbe reduced when in use.

In some embodiments, the urinal screen 110 may function (e.g., alleviatesplash, reduce odor, etc.) within a urinal or toilet independent fromthe orientation of the first frame 114 with respect to the second frame116. For example, the first frame 114 and second frame 116 may havesimilar or identical sizes and shapes which permit the urinal screen 110to function in a substantially similar or identical manner whether thefirst frame 114 contacts the urinal/toilet or the second frame 116contacts the urinal/toilet. Such orientation-independent functionalityand reduce the likelihood of installation error of the urinal screens110.

As illustrated in FIG. 6, the first surface 114 a (e.g., outer surface)of the first frame 114 and/or the second surface 116 b (e.g., outersurface) of the second frame 116 can have a curved or contoured profile(e.g., convex). For example, one or more of the cells on the first frame114 can have a perimeter (e.g., sides 142 a and corners 146 a) havingcurved surfaces 154. The curved surfaces 154 can deflect urine or otherfluids which impact the urinal screen 110. In some embodiments, thecurved surfaces 154 reduce splashing in the urinal or other appliance inwhich the urinal screen 110 is installed.

The curved surfaces 154 can have constant or varying radii of curvature.For example, as illustrated in FIG. 6, the sides 142 a can have amaximum cross-sectional width D. The curved surfaces 154 can have avertical radius of curvature R1. The vertical radius of curvature R1 canbe greater than D/8, greater than D/6, greater than D/4, greater thanD/2, greater than D, and/or greater than 2D. A second radius ofcurvature R2 can be oriented 45 degrees away from the vertical radius ofcurvature in a first direction. The second radius of curvature R2 can begreater than ⅛, greater than ¼, greater than ½, greater than ¾, greaterthan 1 times, and/or greater than 2 times the vertical radius ofcurvature R1. A third radius of curvature R3 can be oriented 45 degreesaway from the vertical radius of curvature in a second directionopposite the first direction. The third radius of curvature R3 can begreater than ⅛, greater than ¼, greater than ½, greater than ¾, greaterthan 1 times, and/or greater than 2 times the vertical radius ofcurvature R1. Many variations are possible.

Similarly, one or more of the cells of the second frame 116 can have aperimeter (e.g., sides 142 b and corners 146 b) having curved surfaces156 which function in the same or in a similar manner to the curvedsurfaces 154 of the first frame 114 if the screen is installed with thesecond frame 116 positioned away from the installation surface.
